@jblackwell I was really surprised as well when it became possible in 5.1 - For the work of an architect like me, this option is really really really wonderful.
I tested with DLSS half a year back but nowadays I don’t anymore. I think it broke at some point and I never bothered again to re-enable it. Will have to try again…
